Article Figures & Data
Figures
- FIGURE 1.
γ-spectrum and photopeak parameters of 99mTc isotope using SW (A) and ASW (B) recorded during whole-body bone scintigraphy. Screenshots are from GE Healthcare Discovery NM/CT 670 workstation.
- FIGURE 2.
SW (left) and ASW (right) whole-body bone scintigraphy in breast cancer patient with coexistence of bone metastases. Widespread foci of abnormal tracer activity are seen within skull, thoracic spine, ribs, shoulders, lumbar spine, and proximal femora in keeping with widespread bony metastatic disease. All readers rated ASW as preferred but not clinically important.
- FIGURE 3.
SW (left) and ASW (right) whole-body bone scintigraphy in breast cancer patient. Thoracolumbar junction region shows minor increased uptake that appears to correlate with degenerative change seen on radiography at T12–L1. One reader rated ASW as preferred but not clinically important. Another reader rated SW as preferred and clinically important because it potentially improves assessment of lumbar spine. Third reader rated neither as preferred.
- FIGURE 4.
Bar graph comparing the pairs of images for all 58 patients. Results are expressed as radiologists 1, 2, and 3 against different imaging scores.
- FIGURE 5.
Bar graph comparing the pairs of images according to patient BMI. Results are expressed as BMI intervals against different imaging scores.
